I've processed a modest 8750 work units in 6+ years. Now it's time to
upgrade my processor for BOINC. For reasons that are not relevant
here, it's to be a Dell Dimensions; either a 9100 or an XPS Gen 5, the
latter billed as the "ultimate gaming machine" (the only game I play
is SETI). The price difference is £500 (not far off $1000), but if I
compare the two side by side I see little difference:
- Same processor; up to Pentium D 840, 3.2GHz, 2x1MB L2 cache, 800MHz
FSB. The 9100 also boasts "with dual core technology", whatever that
is...
- Same memory; dual channel DDR2-533MHz SDRAM.

My Dell 9100 Pentium D 3.0GHz - HT - arrived yesterday. The first
thing I did was to install the classic program with SetiDriver and
SetiSpy. SetiDriver showed max processes 2. I changed it to 4 to take
advantage of HT.
24 hours later and only 20 WUs have been done. SetiSpy shows an
average of 1.8 hours per WU x 20 = 36 hours. Disappointing.
I just rebooted and went into Setup. There I found "Hyperthreading
Capability = NO"!!!
